My experience ordering cross-border ordering internationally: I've ordered from a Canadian pharmacy.

That reframing is the part I needed. I will report back once I have actually tried it.

Clinical perspective, offered as context rather than as advice. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.

Worth answering the question that was asked rather than the one behind it.

I read this differently from NurseLeah_Nash, on substance rather than tone. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

One concrete data point for the thread. One habit that pays for itself: post the method alongside the number. A figure without its method cannot be checked, and an unchecked figure is how this community accumulates folklore.

Ask again with the specifics and you will get a better answer than this one.
